local combi fare

Hi. Just ck'd. your info page for rates and you show 9 pesos as the current min. rate. I used a combi on Friday and was informed the rate is 12 pesos (Merza to Dario Galeana). I said I had not read of the increase on the internet and he pointed to a sheet of paper posted at the bus stop. I didn't stop to read it, but I did walk home. I'll comply when you indicate it's become official. THX
